IMPROVEMENT IN COP-BUILDING MECHANISMS FOR SPINNING-MACHINES.

Specification forming part of Letters Patent No. 195,470, datedSeptember 25, 1877; application filed March 27, 1877.

To all whom it may concern:

Be it known that I, AMASA P. ADAMS, of West Warren, in the county ofWorcester and State of Massachusetts, have invented certain new anduseful Improvements in Spinning- Machines; and I do hereby declare thefollowingto be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

My invention relates to an improvement in cop building mechanism forspinning machines that is adapted to all ring-spinning frames, whetherused for warp or filling; and

of parts, that will be more fully described hereinafter, whereby, first,an attachment is arranged for the purpose of shaping the cop while thebottom is being built, thus causing the cop to. build out to its properdiameter, whereby it is made to take on more yarn than could be donewithout the use of a shaper; second, the combination of parts, wherebythe cop is kept the same diameter from shoulder to shoulder while beingbuilt; third, the change pinion-wheel, whereby it is adapted to allsizes or numbers of yarn fourth, in the application of a building motionto the quadrant, for the purpose of building up the cop the samediameter from shoulder to shoulder, combined with a change pinion wheelfor adapting it to all numbers of yarn.

The accompanying drawings. represent my invention.

it represents an ordinary iron. frame of any desired construction orform. b is a vertical shaft, that is driven by the worm-gear on thefront roll, (shown in Fig. 5,) and which has a bevel-gear, c, secured toits lower end for meshing with the bevel-gear on the'shatt d. On theinner end of this shaft d is secured the heart-shaped cam e, whichbears. down upon a stud or projection from the side: of the lever f forthe purpose of depressing the lever at every revolution. This lever ispivoted at its rear end upon a journal, g, that can be adjusted up anddown in the slotted hanger in which it is held. Formed with, or attachedto, the journal of the pivoted leverf is the arm h, which i is slottedat its upper end; and in this slot is secured the long pawl i, whichmoves the ratchet-wheel j forward one tooth every time the free end ofthe lever f is depressed. The wheel j is placed upon a journal that canbe adjusted back and forth in a slot in which it is held, and whichwheel has a small pinion secured to its side for meshing with thespurwheel is. Pivoted above the wheelj is a dog, I, which prevents anyback motion in the wheel, from any cause whatsoever. Upon the same shaftas the Wheel 70, and turning with it, is the cam m, upon which bears thelong end of the lever n, which is journaled in the bearings 0, which areadjustably secured to the lever f, which is slotted for that purpose.The journal of the wheel is can be adjusted back and forth similar tothe one upon which the wheel j is placed. In the bearings o is placed asetscrew, Q, by means of which the play of the lever n can be nicelyadjusted. To the short end of lever n is attached the chain 1), whichchain connects it with the builder-nut.

As the heart revolves from heel to point the ratchet is carried forward,thereby turning the cam m, whereby the long curved end of the lever 11.is raised and the short end depressed one one-hundredth part of an inchat each revolution of the cam c. This, added to the traverse which theheart gives to the lever f, which is one inch, make one and oneone-hundredth inch traverse.

The chain 1) passes up over the pulley i, that is placed upon an uprightattached to the crossbar 8, and has its other end attached to thebuilder-nut t, so that each time the lever f is depressed the nut willbe drawn forward. Depending from the bar sis a slotted bearing, in whichis clamped a pivot-rod, and upon this rod is placed the pawl n, whichcatches in the teeth of the ratchet-wheel V. Upon the other end of theshaft on which is the ratchet-wheel Vis a bevel-gear,which meshes withthepinion .10, placed on the lower end of the shaft W. Near the upperend of this shaft is secured a bevel-wheel, y, which meshes with thepinion l on the front end of the screw 2, which moves the nut back andforth.

All of the mechanism above described from the ratchet-wheel V is placedupon a frame, 3, which is fastened to the partially-revolving weightedshaft 4. Every time the lever f is depressed the chain draws thebuilding-nut and quadrant t forward, and then, as the lever rises, thecouuterweights 5 draw the nut and quadrant back to position again. Asthe nut is drawn backward again the pawl, which remains stationary,catches behind one of the teeth of the ratchet V, and pulls it slightlyaround, and thereby operates the other wheels, and gradually moves thenut forward on its screw. Extending upward from the shaft 4 is an arm,6, which is connected to a similar arm, 7, that projects upward from aweighted rock-shaft, 8, that runs parallel with the shaft 4. From eachof these shafts project the levers 9, upon which rest the uprights 10,which uprights have the nuts A secured near their upper ends, and uponthese nuts is placed the ring-rail B. As the shafts 4 and 8 rock backand forth, the levers 9 alternately raise and lower the rail upon thespindles.

If desired, the uprights will be provided with flat ends, and the endsof the levers 9 be provided with friction-rollers, so as to make theparts move more easily.

Extending outward from the shaft Sis an arm, which has its outer endconnected, by means of a chain, with a lever, C. By pulling back on thislever the shaft 8 is raised upward, the building-nut and quadrant thrownforward, and the ring-rail depressed and held in this position. By meansof this lever the rail can be moved down when the frame is in fullmotion, and thus the cops are in position, ready to be dofled uponstopping the machine, much better than can be done by hand.

A cop-tube is placed over the top of the spindle Q, low enough down sothat the traveler on the ring R will commence to wind the thread on thetube about one-fourth of an inch from its bottom when the curved end ofthe lever rests in the depression of the cam m. Now, as the heartrevolves from point to heel, and thereby, through the mechanism alreadydescribed, causes the ring-rall to move up and down the length of thetraverse that the heart 'gives to the lever f, which is one inch, and atthe same time that the ring-rail moves up the frame or quadrant 3 moveson a circle to the right, thereby causing the nut t to be worked hack tothe left, (see Fig. 2,) which will give more length to the chain 1), andlet the ring rail up one one-hundredth of an inch farther than before.The heart gives the same length of traverse down that it did up, withthe addition caused by the action and position of the lever n, and thepeculiar shape of the cam m, which, for the sake of illustration, I callthe two one-hundredths of an inch. This two onehundredths added to thetraverse of the lever f makes one and two one-hundredths inch. Thus,every time the ring-rail moves up the builder-nut builds, and every timethe rail moves down the cam mworks around enough to lengthen thetraverse downward, which movement, in connection with the regularup-anddown motion of the rail, tends to give shape or form to the bottomof the cop. By thus lengthening the traverse downward, by the peculiarshape of the cam m and the position of the lever n on the lever f, thebottom of the cop is caused to take on the proper form, and build out tothe right diameter; and this is attained when the cam m has worked aboutone-third of the way around from where it first started. The othertwo-thirds of the cam holds the body of the cop at the proper diameteruntil the full length is attained.

Having thus described my invention, I claim- 1. In a spinning-machine,the combination, with the ring-rail and mechanism for imparting to thesame a reciprocating motion, of a builder-nut, an auxiliary cam, andmechanism, substantially as described, for operating the saidbuilder-nut and for connecting the said cam to the rail, whereby, in theoperation of the machine, the traverse of the rail is raised at eachtraverse thereof, and the form of the initial cone is regulated, as andfor the purposes set forth.

2. The combination of the heart 0 and an intermediate operatingmechanism between the heart 0 and cam m, substantially as described,with the two levers f and n, and a builder-nut, the parts beingconnected 'and arranged to operate as described.

3. In a cop-building mechanism,'the combination of the lever f, heart e,arm 11., pawl i, lever n, cam m, and intermediate mechanism,substantially'as shown.

4. In a cop-building mechanism, the combination of the lever f, lever n,arranged on the top thereof, heart 0, intermediate mechanism,substantially as described, cam 3n, chain 12, and a building-nut,substantially as set forth.

5. The combination of the pawl u, ratchet V, shaft W, suitableconnecting-wheels, screw 2, and buildingnut t, substantially asdescribed.

6. The combination of the weighted shaft or shafts, levers 9, uprightsl0, and ring-rail B, with an arm and lever attached to the shaft,whereby the rail can be lowered when the frame is in full motion,substantially as specified.

In testimony that I claim the foregoing I have hereunto set my hand this17th day of March, 1877.
